RAZOR-BLADE HOLDER.

Application filed August 16, 1920, Serial No. 403,907. Renewed October2, 1922. Serial No. 591,986.

To all whom it may concern:

Be it known that I, CLiNroN A. Soon, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Razor-Blade Holders, ofwhich the following is a full, clear, concise, and exact description.

My invention relates to devices for so holding safety razor blades thatthey may readily be applied to hones or other sharpening elements.

The device includes, as one of its characteristics, two pivotallyconnected jaws that are pressed upon an interposed blade by a spring orsprings of U-form with means for limiting the opening movement of thejaws to preserve the set'of the springs. These jaws are pivotallyconnected by means of a sleeve rivet which assembles them into a unitindependently of the handle that is afterwards assembled therewith by ariveting pin passing through prongs of the handle and the bore of theriveting sleeve. There are other characteristics, the invention beingmore fully explained in connection with the accompanying drawing showingthe preferred embodiment thereof in which Fig. l is a plan view withparts broken away; Fig. 2 is a sectional view on line 22 of Fig. 1; Fig.3 is a view in elevation with parts of the handle broken away; Fig. 4 isa sectional View on line 4.4c of Fig. 1; Fig. 5 is a sectional view online 55 of Fig. l on a larger scale; Fig. 6 is a sectional view throughthe ball hearing cup and parts therein; and Fig. 7 is a plan view of asmall ball retainer.

Like parts are indicated by similar char acters of reference throughoutthe different figures.

The blade gripping jaws 1 and 2 are pivotally connected between theirfront and rear ends by a riveting sleeve 8 which is passed throughaligned holes in the lateral outer wings 4 of jaw 1 and wings 5 of jaw 2that are between wings 1. This riveting sleeve constitutes a bearingupon which the wings turn when the jaws are in opening or closingmovement. In assembling the sleeve rivet with the jaws it is passedthrough the b-ights of the rearwardly extending U-shaped wire springs 6that are prevented from being withdrawn by said rivet. The springsengage the inner opposed surfaces of the jaws at the rear of their pivotto force the front edges of the jaws into clamping engagement with thesafety razor blade 7. The set of each spring is increased by bringingthe sides of the spring very close together, the spring still beingengageable with the jaws by forming the springs with lateral or offsetjaw engaging extensions 8.

The front edges of the aws may be separated for the insertion andremoval of the blades by pressing the rear ends of the jaws toward eachother in opposition to the springs. The set of the springs is preservedby a distance preserving formation that limits the approach of the rearends of the jaws. This formation is preferably an extension 5 upon eachwing 5 of the jaw 2 and at the rear of the rivet 8, these extensionsbeing engageable with the opposite jaw when the front edges of the jawshave been separated a slight distance sufficient to permit of themovement of the blade in the space between the front ends of the aws.

The handle is preferably split, being formed in two half portionsstamped out of sheet metal. These handle portions are held in assemblyby a cap or collar 9 tightly driven upon their rear ends, and a rivet 10passing through and riveted upon the halves of the handle where thehandle prongs 11 branch one from each half of the handle.

The riveting sleeve 3 is aligned with holes in the tips of the handleprongs, whereafter a riveting pin 12 is passed through the bore of theriveting'sleeve and the holes in the handle prongs, being thereafterriveted to assemble the handle with the jaw unit, said riveting pinconstituting a small shaft upon which the riveting sleeve turns as thejaw unit is swung in the blade sharpening operation. The rangeof-swinging movement of the jaw unit is limited by the stem portion 13of the T-shaped element 10-13, this stem portion projecting into thespace between the rear ends of the jaws 1, 2.

Each jaw includes as a structural part thereof an insetting cup 14 uponthe rear end thereof, a protruding ball 15 that rolls within the ballretaining cup upon smaller rotating balls 16 confined to centers ofrotation by being received in the notches 17 of a retainer 18. The ballportion 15 of each jaw defines the angle of the blade 7 to thesharpening element. These balls make the ends of the jaws to the rear ofthe pivot pin 12 heavier than the front ends so that whenever the handleis turned to reverse the blade the jaw unit will quickly turn toapproximate the working angle to the hone and handle, this movementbeing limited by the stop 13.

Having thus described my invention 1 claim as newand desire to secure byLetters Patent.

1. A device for holding a safety razor blade that is .to be sharpenedincluding a pair of blade clamping jaws having lateral wings formed withaligned holes, the wings ofone jaw being received between the wings ofthe other jaw; a riveting sleeve passing through the wings and assembledwith the outer wings and upon which the inner wings may turn; a handlehaving prongs; a pin extending through the riveting sleeve that may turnupon the pin which is secured at its ends to said prongs; and arearwardly extending U-shaped spring through which the riveting sleevepasses, the ends of the spring pressing against the inner faces of therear portions of the jaws to exert closing pressure upon the jaws.

A device for holding a safety razor blade including pivotally connectedblade clamping jaws; split handle having two prongs, one upon each partof the handle, upon which said jaws are mounted to turn as a unitbetween their forward and rear ends; and a T-shaped element adjacentsaid prongs and whose head portion constitutes a rivet that unites thehandle parts together adjacent said prongs and whose stem portionextends into the space between the rear ends of the jaws to limit theswinging movement thereof upon the handle.

a. A device for holding a safety razor blade including pivotallyconnected blade clamping jaws; a handleupon wvhich said jaws are pivotedbetween their forward and rear ends to swing as a unit upon said handle;and a rearwardly' extending U- shaped spring, the ends of the springpressing against the inner faces of the rear'portions of the jaws toexert closing pressure upon the jaws, said spring'beinglaterallyextended to decrease the space between its sides while maintainingengagement with the jaws.
